A varied diet is not only good for your waistline but it can also be good for the mind.

Researchers in Tehran, Iran, have investigated the relationship between a diverse daily diet and depression in women attending health clinics, discovering the more varied the less severe a depression risk.

The study involved 360 women, between the ages of 20-49 years old, who attended 10 different health centres. The women were asked to do a questionnaire that allowed them to be classed into three groups: normal mood, mild or moderate depression, or severe depression.

Can Hugs Help Keep You Healthy?0:52

Mounting scientific evidence seems to suggest that hugs are good for your health. They lower blood pressure which is a risk factor for heart disease. Oxytocin, the chemical released by the brain while hugging, is being investigated as a treatment for various conditions, including depression.

Participants also completed a questionnaire on the food they had consumed in the last 24 hours.

Researchers then created individual Dietary Diversity Scores (DDS) based on the food groups the women ate.

They found that a one-unit increase in the Dietary Diversity Score led to a 38 per cent reduction in the risk of severe depression. However, no association was found between the DDS and mild or moderate depression or stress.

The authors noted that the study has some limitations – it was small and the 24-hour food period only provided a snapshot of individual’s diets – and needs further research. They also didn’t rule out the idea a lack of variety in a diet could be the consequence rather than the cause of depression.

Yet, despite these limitations, they say the findings are in line with other studies which indicate a balanced diet can protect against depression.
